Learning outcomes

Students will learn basic concepts about the fundamental algorithms to solve well knwon computational problems, and the basic data structures and abstract data types, as well as techniques for evaluation of computational complexity of algorithms (and computation complexity classes P, NP, NP-hard) and space complexity of algorithms execution (memory space). The course will offer the illustration of trade-offs and sinergies between algorithms and data structures, and a training on methodologies to realize the design of efficient algorithms and correspondingly appropriate data structures to solve both generalized and specific instances of computational problems, under pre-defined assumptions and requirements.

Teaching methods

Classroom lecturers with projection of electronic slides, exercises, homeworks and projects.

Assessment methods

The assessment consists in a final written examination, lasting 3 hours. The purpose of the written exam is to check the practical ability to design correct and efficient algorithms to solve computational problems, and to verify that the expected theoretical knowledge has been acquired.

The written examination may be replaced by the development of projects that, once positively assessed, (must obtain an assessment ≥ 18/30), will be discussed with the teachers.

Teaching tools

All course material (lecture slides, exercises and other resources) will be made available on the course web page.
